How to remember the currently opened page in the pagination of the membersloop in Buddypress, so when visiting a profile and coming back to the membersloop, it gets opened on that page?
I saw that in buddypress-nouveau.min.js?ver=1.7.8:formatted the ajax call is done via the JS function objectRequest() but it gets called with the "page: 1" parameter as a fixed value.
Is there a way to override this?

I have a REST Url http://localhost/issues presenting me a search form for querying issues of a bug tracker system. The search form has a textfield with name="f". The action of the form is action="/issues" and the method=GET. So if I type "foobar" into the textfield, I am getting redirected to http://localhost/issues?f=foobar.
To prevent page reload, I use AJAX with jquery. So I used $(document).on('submit',...) to bind an AJAX query function to the submit function of the form. I used firebug to proove, that jquery sends the request and no page reload is taken. I also have a function to fill results of the response into my site presented in the browser. Everything works fine for the first search attempt.
But if I type another search string "anotherfoobar" into the textfield and resend the request, the request URL is http://localhost/issues?f=foobar&f=anotherfoobar, so the search parameter is only appended to the URL, not updatedas I thought it would happen.
I've read about "hashing" the URL parameters to prevent this behaviour here on stackoverflow, but do not fully understand what and why this is happening and what "hashing" means exactly. Perhaps it's not the right solution for me. So I kindly ask someone to explain me how I can solve this.
I've solved it! Don't ask how exactly, what I did was the following:
The AJAX response is the whole Web page as I would get it with a page reload. with jquery I select a div which includes the search form AND the results.
I simply defined a div only for the results, and update only the content of the results div. After doing so, everything works fine, and the results div updates with multiple search attempts.
Another case of not knowing what I do, but I do it fine ;)
Perhaps someone still can explain me my error so wisdom can rise.
From my view I am sending via $.ajax a JSON object to my controller to save it in the database.
If all succeeded i want to redirect to another action which will show a diferent view.
If i use this code:
return RedirectToAction("CreatePage", "Survey", new {id = question.PageId});
The execution goes to the Survey controller which returns a view but it is not shown.
I have read some post which said that it is not posible to redirect via ajax.
The solution I use so far is to redirect via javascript like this:
success: function (ret) {
window.location.href = "/Survey/CreatePage/" + $("#PageId").val();
}
Although this always works, sometimes i need to refresh the CreatePage view to show the last changes made.
Any idea of how to solve this problem better?
Thanks in advance
As mccow002 suggested, I wasn't really needing to make the call via AJAX for that part. After studying the solutions suggested, i realized that i could simple submit it in a form. My confusion came because I have a save and continue editing and a save. For the save and continue I use the AJAX call, but for the save option with the form being submitted is ok.
Thanks very much for your help.
Instead of redirecting to a new page, you can send a rendered html from .net code back to client and load that html in page, like this $("#main").load(renderedHtml).
But for refreshing the page you can write a simple script that run at specified intervals and refresh the page contens.
You could use [OutputCache] on the CreatePage action so that it doesn't cache the page or only caches for so long.

I have a mobile site which completely runs using AJAX, and hash code, basically each page click is a link, such as
<a href='http://some-domain.com/my-page-122.php" hash-id='122'>linkage</a>
Meaning that the page itself exists and it has ON IT google analytics page, HOWEVER, on the ajax request, I only ask to load a certein <div> on said page using jQuery's load(), so my question is:
because the page is called for in it's entirety with the google analytics code and everything, will it still record it as a page view even though only a portion is injected to the page?
The reason why I'm asking is because this site is getting around 500 uniques per day, and we want to change it to this new AJAXy form, so not recording analytics is a big no-no.
If you use jQuery you can bind to the global AjaxComplete event to fire a Pageview everytime an Ajax call completes:
jQuery(document).ajaxComplete(function(e, xhr, settings){
var d = document.location.pathname + document.location.search + document.location.hash;
_gaq.push(['_trackPageview', d]);
});
If you update the Anchor every time you do an Ajax call this will fire the full path including the anchor part of the url.
Note that if you load content using .load that has the Google Analytics Tracking code in it, it will run that code and fire a second pageview. So you want to make sure you don;t include the GATC on the ajax content to avoid double pageviews.
Analytics won't record it automatically. Assuming you're using the asynchronous code you can record as many pageviews as you want by writing to the gaq array using an explicitly set URL:
_gaq.push(['_setAccount', 'UA-12345-1']);
_gaq.push(['_trackPageview', '/home/landingPage']);
In this case you can build whatever URL you want where they have '/home/landingPage'. Note that if _gaq was already properly instantiated and _setAccount was already pushed then you only need to push the _trackPageview.
Also, the event can be in code returned by your AJAX, or it can be in the click event of your button or whatever is launching the AJAX request.
See http://code.google.com/apis/analytics/docs/gaJS/gaJSApiBasicConfiguration.html#_gat.GA_Tracker_._trackPageview
I am trying to use CodeIgniter and jQuery-ui dialog to create a modal window with form to update user information.
The process should be like:
1. Press a button on a view page.
2. A modal window pops up.
3. Inside the window is a form that a user can fill.
4. If the user filled something before, the information should be shown in corresponding field
5. Click the update button on the modal window to save the changes to database.
Can anyone provide a good sample of this process?
I used ajax to pass the data but it didn't work when I was trying to update the data to the database. It would be nice if an example of how to pass data from ajax to php and how php handle that.
Thanks,
Milo
well the jquery bit for post(), get(), ajax() works the same in any measure you would normally use it.. key difference here is with CI you can't post directly to a file-name file-location due to how it handles the URI requests. That said your post URL would be the similar to how you would access a view file normally otherwise
ie: /viewName/functionName (how you've done it with controllers to view all along. post, get, ajax doesnt have to end in a extension. I wish I had a better example then this but I can't seem to find one at the moment..
url = '/home/specialFunction';
jQuery.get(url, function(data) {
jQuery("#div2display").html(data);
});
in the case of the above you notice despite it not being a great example that. you have the url with 2 parameters home and specialFunction
home in this case is the controller file for home in the control folder for the home file in views the specialFunction is a "public function" within the class that makes the home controller file. similar to that of index() but a separate function all together. Best way I have found to handle it is through .post() and a callback output expected in JSON cause you can form an array of data on the php side json_encode it and echo out that json_encode and then work with that like you would any JSON output. or if your just expecting a sinlge output and not multiples echoing it out is fine but enough of the end run output thats for you to decide with what your comfortable doing currently. Hopefully all around though this gives you some clairity and hopefully it works out for you.
This is probably going to get a resounding no, but I am wondering if it possible to have the URl change dynamically with using hashing, and without invoking a http request from the browser?
My client is keen on using AJAX for main navigation. This is fine, when the end user goes to the front page first, but when they want to use the deep linking, despite it working, it forces an extra load time as the page loads the front page, then invokes the AJAX from the hash.
UPDATE: Could it be possible, given that what I want to avoid is the page reload (the reason is that it looks bad) to stem the reload by catching the hash with PHP before the headers are sent, and redirecting before the page load. This way only one page loads, and the redirect is all but invisible to the user. Not sure how to do this, but seems like it is possible?
Yes, this is possible. I often do this to store state in the hash part of the URL. The result is that the page doesn't reload, but if the user does reload, they're taken to the right page.
Using this method, the URL will look like: "/index#page=home" or "/index#page=about"
You'll need to write a JavaScript function that handles navigation, and you'll need a containing div that gets rewritten with the contents fetched from AJAX.

<div id="content"></div>
<script type="text/javascript">
function link(page) {
location.hash = "page="+page;
loadPage(page);
}
// NOTE: This is using MooTools. Use the AJAX method in whatever
// JavaScript framework you're using.
function loadPage(page) {
new Request.HTML({
url: "/ajax/"+page+".html",
onSuccess: function(tree, elements, html) {
document.id('content').setProperty('html', html);
}
}).get();
}
</script>
Now, you'll also need to have something that checks the hash on page load to load the right content initially. Again, this is using MooTools, but use whatever onLoad method your JavaScript framework provides.
<script type="text/javascript">
document.addEvent('domready', function() {
parts = location.hash.split('=');
loadPage(parts[1]);
}
</script>
Ok, the problem is that opening an AJAX link of the form http://example.com/#xyz results in a full page being downloaded to the browser, and then the AJAX-altered content is changed once the page has loaded and checked the hash part of its URL. The user has a diconcerting experience.
You can hugely improve this by making a page that just contains the static elements - menus, etc. - and a loading GIF in the content area. This page checks its URL upon loading and dynamically fetches the content specified by the hash part. The page can have any URL you want; we'll use http://example.com/a. Links to this page (http://example.com/a#xyz) now provide a good user experience for users with scripting enabled.
However, new users won't come to the site by fetching http://example.com/a; they'll fetch http://example.com. This is fine - serve the full page, including the home page content and links that don't require scripting to work (e.g., http://example.com/xyz). A script run on loading this page should alter the href of AJAXable links to their AJAX form (http://example.com/a#xyz); thus the first link a user clicks on will result in a full page load but subsequent ones won't.
The only remaining problem is is a no-script user gets sent an AJAX link. You can add a noscript block to the AJAX page that contains a message explaining the problem and provides a link back to the homepage; you could include instructions on how to enable scripting or even how to modify the link by removing a# and pressing enter.
It's not a great answer, but you can offer a different link in the page itself; e.g., if the address bar shows /#xyz you include a link to /xyz somewhere in the page. You could also add a link or button that uses script to bookmark the page, which would again use the non-AJAX form of the link.
